My sky booster is not connecting

[NaheedNabi]

The sky booster was moved further away & as the 2nd tv was not used in a while no issue was noted.

When we tried to turn the 2nd tv on which had a mini Sky Q box it would not work 

we moved the booster back to its original place but it's still not showing as connected. Only 2 green lights are on, the power light & Wifi
